In this paper, we present on the research of semantic-based 3D model retrieval system and its developed framework. We use RDF annotation to label 3D models for improving retrieval precision. The framework contains three parts: preprocessing, feature extraction and similarity measurement. The parts are recommended to analyze the 3D model. In the preprocessing part, we deploy PCA to make models normalization...
Traditional methods to modeling semantic similarity only compute the common characteristics and uncommon characteristics, without considering the structural relationship between concepts. In this paper, a new semantic similarity method based on information content is proposed. It evolves from feature model, the function λ in the algorithm which defines the relative importance of the uncommon characteristics,...
A novel modeling method is presented in this paper to measure the similarity between short texts. We thought that the complete expression of a sentence or a short text, not only depends on the words, but also relies on the syntactic structure, thus the method takes word similarity feature and syntactic feature into account. The proposed method can be used in a variety of applications involving automatic...
